Elastic Cartilage is one of three types of cartilage found in the human body. It is a form of connective tissue. The matrix is dominated by a dense network of elastin fibres. Elastic cartilage provides support with moderate elasticity. It is found mainly in the larynx, the external part of the ear (pinna), and the tube leading from the middle part of the ear to the throat (eustachian or auditory tube). We can see visibly in the slide the different labeled parts. First is the perichondrium, which is usually found around the perimeter ofelastic cartilage and hyaline cartilage. Perichondrium is a type of irregular collagenous ordinary connective tissue, and also functions in the growth and repair of cartilage. Second is the lacunae that contains chondrocytes. The cartilage cells or chondrocytes are contained in cavities in the matrix, called cartilage lacunae; around these, the matrix is arranged in concentric lines as if it had been formed in successive portions around the cartilage cells. Last is the Elastic Fiber, which are bundles of proteins (elastin) found in extracellular matrix of connective tissue and produced by fibroblasts and smooth muscle cells in arteries.
